Abstract

Chinese Train Control System Level 3 (“CTCS level 3”for short) is an advanced train control system applied to high-speed railway, especially for the Passenger Dedicated Line, whose speed is wanted to reach 350Km per hour. Establishing the CTCS hardware-in-the-loop simulation (“HILS”for short) system is important for the reasons listed below: the system can provide effective testing and verifying technical support environment for developing, manufacturing and integrating of concerned equipments, and it is very helpful for realizing system-level test and verification, which is very important because it can find system-level faults and integrating errors that cannot be find by conventional equipment-level test. The geographic information model is the supporting system for the whole hardware-in-the-loop simulation platform, it provides basic running environment for the train model and on-board equipment models, so it is an important part of the simulation system.In this thesis, the function requirement of geographic information system of high-speed railway is fully analyzed. Using Object Oriented modeling method and meta-modeling ideology, a meta-model based modeling method for railway geographic information is proposed. The modeling principle, modeling scheme and key technologies are deeply explained and different modeling schemes are compared in detail. Using this modeling method, the railway geographic information can be expressed more concisely and completely, and the model can be extended and reconstructed more easily. As a result, the geographic information model is successfully used in the CTCS HILS system and provides effective running environment for train model and on-board equipment models. It also provides a strong base for realizing auto test of train control equipment and system.In this thesis, the software realization of the geographic information model is also studied. Using OO software architecture, according to the application characteristic of railway line simulation and the modeling method proposed in this thesis, adopting basic-line as meta-model, the software is developed by Java programming language and Eclipse developing environment. In another aspect, according to the requirement of the geographic information model, a database for geographic information on the railway is established, providing instantiation data for the geographic information model; to display the real-time running status of the trains and the related equipment on the railway, and providing observation and control interface for train running, the line display interface is designed and implemented.The geographic information model for high-speed railway is instantiated by real railway-line data, and real railway-line diagram is adopted and showed by the the line display interface. Nowadays, the geographic information model has been applied to the laborary test of the WuHan-GuangZhou Passenger Dedicated Line, and it provides a strong base for simulation and testing of the CTCS.
